Philosophy (Humanities), 1955

A handy placeholder term to put in front of any “ism” word you invented, indicating progress and edgy “discourse”; regardless if it has any merit or makes any sense. The most intellectual™ kind of “discourse”.

Postmodernism (anti-modernism), post-Structuralism (anti-Structuralism), post-Postmodernism (anti-Postmodernism), post-materialism (anti-Materialism), post-colonialism (anti-Colonialism), post-Genderism, post-humanism, post-Contemporary, post-Hegemony, post-Theism, you name it. After 1955, it’s been The Thing to put before your new set of bad French philosophy ideas to disguise your dislike for the values you want to “critique” because they’re no longer fashionable — but you don’t want to sound mean. Hopefully, soon, the dawn will begin of Post-[Stupid]ism.

Or as so beautifully put on Urban Dictionary:

“Postmodernism is the ultimate lubricant invented by social sciences in order to fuck every concept and structure that humans ever came up with. At the same time it is used as a means for social sciences to penetrate one another.”
